The Reappearing Masterpiece: Ranking American Artists and Art Works of the Late Twentieth Century

A survey of the illustrations in textbooks of modern art produces the startling finding that art scholars consider Robert Smithson's Spiral Jetty to be the most important individual work made by an American artist during the past 150 years. More generally, quantifying the evidence of the textbooks reveals the source of the pluralism, or stylistic incoherence, of American art since the late 1960s. A persistently high demand for artistic innovation has produced a regime in which conceptual approaches have predominated. The art world has consequently been flooded by a series of new ideas, often embodied in individual works, usually made by young artists who have failed to make more than one significant contribution in their careers. The monumental Spiral Jetty, made in 1970 by a young artist who was killed soon thereafter while in the process of making his art, brought together a remarkable number of the central themes of the advanced art of the time and has become a symbol for that art.     

The spiral that vanished: the application of non-contact recording techniques to an elusive rock art motif at Castlerigg stone circle in Cumbria

This article describes the recording of stone 11 of the Castlerigg stone circle in Cumbria through two different non-contact techniques: laser scanning and ground-based remote sensing. Despite the unproblematic recording of modern graffiti, neither technique was able to document the spiral photographed and rubbed in 1995. It is concluded that the spiral was most probably painted and has since faded away due to natural events. The discovery and loss of the spiral motif in Castlerigg is seen as a cautionary tale. In particular, it seems to suggest that it is time to take advantage of the novel technologies based on the digitisation of 3D surfaces with millimetre and submillimetre accuracy such as laser scanning and ground-based remote sensing. They offer many advantages to the recording of prehistoric carvings. In addition to avoiding direct contact with the rock surface eliminating the preservation concerns raised by other techniques, both produce high quality images (laser scanning offering a greater potential for this, but at higher cost) having a much higher level of objectivity, and precision and accuracy far beyond those of traditional recording methods such as wax rubbings and scale drawings.     

网络游戏旅游开发模型设计初探

网络经济时代,随着地理区位的弱化,传统地理学面临着如何在网络经济领域找到切入点的问题。本文以"天龙游"推出为契机,探讨网络游戏旅游这种新的旅游形式,以此作为地理学的切入点和传统旅游产业的创新点之一。由于网络游戏是一种特殊的旅游资源,不能同于传统资源的开发方式,所以本文尝试设计了一个新的开发模型-螺旋模型,并重点阐述了该模型的应用流程。
